Abstract

This paper investigates the Chinese stock market reactions to the announcements of Covid-19 vaccine approvals. These announcements generally impacted stock prices, but the impacts appeared to be heterogeneous across sectors. Particularly, firms in the manufacturing, wholesale, retail, and information technology sectors were persistently benefited. We also find that firms with poorer performance, smaller sizes, and greater ages reacted more positively compared to others.
